A. Write an equation for the rule to calculate each of the following costs for any number, n, of customers.
1. bike rental 2. Food and camp costs 3. Van rental
1. 1.BRC= 30 x n 2. FCC= 125 x n 3. VR= 700
B. Write an equation for the rule to determine the totalcost for any number, n, of customers. TC= (30 x n) + (125 x n) + 700
C. Write an equation for rule to determine the profit for any number, n, of customers. P= (350 x n) – (30 x n + 125 x n + 700)
